Article Summary
Today's weather on HD 189733 b: It will be hazy with high wispy clouds. The wind will be steady from the east at speeds approaching 6000 miles per hour. Daytime temperatures will average a balmy 800 degrees C (1,472 degrees F), while the equatorial hot spot at 30 degrees longitude is expected to top 900 degrees C (1,652 degrees F). But, there is a high chance of silicate snow showers, with accumulations expected except in the vicinity of the hot spot.
